REVERSIBLE WINDOW.

Application led November 27, 1926. Serial No. 151,041.

This invention relates to a new and useful device'in the nature of a rotatable window frame, particularly adapted for use in windows such as generally used for bulldmgs of all classes, so as te permit the window glass to` be cleaned on the outside without necessitating the hazardous task of climbing on the outer ledge of the window.

The object of the invention is to provide a rotatable window frame of novel construction and arrangement of part-s, hereinafter more fully tlescribed, Claimed and illustrated in the accompanying drawings, in which:

Fig. 1 shows m improved device as viewed from the inslde of the building.

Fig. 2 is a longitudinal view taken on the line 2-2 of Fig. 1.

Fig. 3 shows an enlarged fragmentary detail view of my improved device, partly in section, so as to expose the working parts thereof.

Fig. 4 shows an enlarged detail View of the locking and releasing mechanism.

Fig. 5 shows a sectional view taken on the line 5-5 of Fig. 4.

Fig. 6 shows an enlarged detail sectional view thereof.

Fig. 7 shows an enlarged detail view of the releasing plungers.

Fig. 8 shows a sectional view taken on the line 8-8 of Fi 2.

As here embo ied my improved rotatable window frame comprises a pane of glass 10, mounted in the frame proper 11, in the usual well known manner. The frame proper 11. has attached thereto, extended elements 12, adapted to engage in apertures formed in the side members 13. The extended elements 12, are provided with enlarged heads 14, so as to insure the engagement of the extended elements 12 in the side members 13. The above described construction being such as will permit the frame proper 11 to be rotated, so as to permit the pane of glass 10 to be washed on the outside surface thereof, by a person in the inside of the building.

The side members 13 are provided with extremities 14, adapted to slidably engage in elongated slots formed in the extremities of the upper and lower members 15 and 16. The releasing plungers 17 are slidably mounted in the casin s 18, positioned in apertures formed in t e side members 13, and in the upper and lower members 15 and 16. The expansion springs 19 are positioned in the casings 18 below the releasing plungers 17 so Aas to normally urge the side members 13, and the upper and lower members 15 and 16 outwardly, so as to permit the said frame proper 11 to be rotated. It being understood that` tlieframe proper 11 is provided with grooves 20, adapted to be I engaged by the projecting element 21 of the side members 13, and the upper and lower members 15 and 16, so as to prevent the frame proper 11, from being rotated when the latter mentioned elements are engaged.

The flexible member 22 is attached to th wheel 23, rotatively mounted in the plates 23 and 24, positioned in an aperture formed in the lower member 16. The flexible member 22 is'extended over the pulleys 25, rotatively mounted in the side members 13, the lower and upper members 16 and 17. The latter described construction being such as will permit the side members 13 and the lower and u per members 16 and 17vto be forced or pu led inwardly, so as to engage the frame proper 11, when the wheel 23 is rotated or turned by the key 26, adapted to engage the shaft 27 attached to the said wheel 23.

The ratchet 28 is attached to the wheel 23 and is adapted to be engaged by the leaf spring 29, attached to the lower member 16,

so as to hold the wheel 23 in the desired position.

The releasing knob 30 is rotatively mounted in the plate 23 and is provided with extended elements 31 and 32, adapted to engage the leaf spring 29, so as to release the wheel 23, so as to permit the releasing plungers 17 to force the side members 13 and the lower and upper members 16 and 17- outwardly, which will permit the frame proper 11 to be rotated for the purpose as hereinbefore set forth. The side members 13 are attached to the lower and upper members 16 and 17, by the links 33, provided with elongated apertures 34, so as to limit the disengagement of the frame proper 11.

It will be understood that the side members 13 are slidably mounted in the casing 35, such as is commonly provided to receive the window frames.

The casing 35 is provided with a lower aperture 36, adapted to receive the lower member 16,-when the slide 37 is pulled outwardly by the knobs 38, handles or the like attached thereto. The latter described construction being such as will permit my improved device to be lowered, as .will be required, to permit the upper window frame to be released and rotated.

Having 'thus described my invention, what I claim as new and desire to protect by Leters Patent of the United States is as folows:

1. A rotatable window frame com rising a window frame proper, a pane o glass mounted therein, said window frame proper rotatively mounted in side members, said side members slidably engaged in upper and lower members, said side members and said upper and lower members, adapted to slidably engage in a window casing.

2. In a rotatable window frame of the class described, side members adapted to slidably engage upper and lower members, releasing plungers slidably mounted in apertures formed in the said side members and in the said upper and lower members, expansion springs normally urging the said side members and the sald upper and lower members outwardly, a frame proper rotatively mounted in the said side members.

3. In a rotatable window.frame\ of the class described, a flexible member attached to a wheel rotatively mounted in a lower member, said flexible member extended over ulleys rotatively mounted in side members, m the said lower member and in an upper member, as a means of forcing the said side members and the said lower and upper members inwardly, when the said wheel is rotated.

4. In a rotatable Window frame of the class described, a ratchet, said ratchet engaged by a leaf spring, a releasing knob adapted to release a wheel, so as to permit releasing plungers to outwardly urge side members, and lower and upper members, a frame proper rotatively mounted in the said side members.

In testimony whereof I have ailixed my signature.
